ADJUSTABLE ACT-USN FOR PIANO PLAYERS.

To all whom it mag concern:

Be it known that I, E GEXE T. TURNEY, a

city, county,'and" State of New York, and

,whose post-office address is No. 2595Third avenue, New York city, have invented new and useful Improvements in Adjustable Actions for Piano-Players, of which the following is a specification.

. j The present invention relates to a mecha- In my Patent No. 1,028,308, June 1, 1912, I have described an arrangement of wind chest, pneumatic and piano action for pneumatic piano players designed to permit'eas y" ad ustment of the relation of the pneumatlc mechanism with the piano action.

nism for securing a similar result with certaln advantages of convenience, 1n construct on and in use referred to in deta l hereinafter.

The accompanying drawings illustrate an embodiment of the invention. Figure 1 1s a transverse vertical section of the mechanism showing the pneumatics and the stickers of the piano'action in side elevation. and the shoes in section. Fig. 2 is a front elevation of the same.

Referring to the embodiment of the invention illustrated the pneumatic mechanism comprises a'series of wind chests A all-ranged one above the other, a slight dis tance in front o-fthe Stickers 3 which com-. inunicate motion .to the hammers of the piano in any usual or suitable way. These.

stickers operate upon the hammers by an upward movement and are held against any I substantial amount of horizontal movement.

Upon the backs of the Wind chests A- are the several. pneuma'tics C eacharranged in line with one of thestickers B and having a movable member D which is pivoted upon" its lower edge" and is adapted to be swunginward when the proper valve mechanism in the wind chest is operated. The movement of the pneumatic is communicated to itssticker'by means of an approximately lIOI'I zontal arm E fastened to the movable mem- ;ber- D of the pneumatic near its hinge and projecting rearwardly so as to bring its rear Specification of Letters Patent.

end-under a shoe attachedto the sticker. To 7 I "secure aproper co-action between the mot?- able member of the pneumaticand the piano ,ggetign a nie adjustment of the relat on be I The principal purpose of this invention is' to provide for such adjustment by making Patented Jan. 2.12191 e Application filed November 21, 1913.

the shoe onthe sticker movable through a 1' device which is easily accessible. and operable from the, front of the apparatus. The

shoe F, provided with a felt G, is pivotally.

mounted on the sticker B, the pivot pin H being carried in a block J which is screwedat a proper elevation upon the sticker. The 1 contact end of the shoe is rounded as shown and the shoe may be swung slightly up and down about its pivot in order to secure the desired adjustment. "For this purpose the shoe is connected to a.downwardly extend ing arm K, the lower end of which is engaged by a collar or shoulder L on ascrew M which extends in a substantially horizontal direction inline withthe space between.

the pneumatic C to whichjt belongs and that in the next lower row; the threads ofthe screw extending into the sticker'B,'so that as the screw is turned it brings the shoe F down upon the arm E of the pneumatic and efi'ects the desired adjustment. The screw in the position described is capable of easy engagement by the socket of-a long ,screw' driver which fits the screw head. An operator, therefore, standing at the front of the action can readily adjust the shoes on the stickers to bring them into proper engagement with the Pneumatics. The locating of the adjusting device on the sticker, which is practically immovable horizontally, permits' a quicker adjustment than. with my previously patented device, in which the adjusting screw was on a movable member of the pneumatic, and, therefore, mightyield 1 to the pressureof the adjusting screw driver.

The ad usting device is entirely in the rear of the pneumatics and operating arms E so that it may have whatever vertical move,

ment is necessary. The vertical space between successive pneumatics C. however, need only besuflicient to admit the blade of the screw driver and should register with theadjusting screw when the sticker is in its lowest position.

adapted to operate the stickers and means for effecting an adjustment of the relatiye positions of the contacting parts of the stickers and their pneumatics, said adjusting means comprising screws attached to the stickers, extending horizonially, and located, when the stickers are at rest, in line with spaces between the pneimatics so as to be readily accessible for adjustment from the front.

2. The combination with stickers and pneumatics of a player piano, of means for e'ltecting an adjustment of the lelative positions of the contacting parts of the stickers and the pneumatics, said adjmting means comprising 'a shoe carried by the sticker and adapted to he engaged by the movable member of the pneumatic and an adjusting device for said shoe including a horizontal having-a threaded engagement with said sticker and having a shoulder engaging said arm.

In witness whereof, I have hereunto signed my name in the presence of two subscribing Witnesses.
